Cavity disinfection in minimally invasive dentistry - comparative evaluation of Aloe vera and propolis: A randomized clinical trial.

Prabhakar AR, Karuna YM, Yavagal C, Deepak BM - Contemp Clin Dent (2015)

Bottom Line: In all the three groups, significant amount of bacteria were left behind after hand excavation.Hand excavation alone does not completely eliminate bacteria, which may predispose treated teeth to secondary caries.Both propolis and A. vera extracts can be used as potential natural disinfecting agents, thereby embracing the concept of phytotherapy in minimum intervention dentistry.

ABSTRACT

Context: The survival of atraumatic restorative treatment (ART) restorations would probably increase if near total elimination of cariogenic microorganisms could be done in the process of cavity cleaning before going ahead with the restoration. Thus, use of naturally occurring disinfecting agents for achieving this goal could herald a new beginning in the field of contemporary minimum intervention dentistry.

Aims: To evaluate the efficacy of hand instruments in excavating dental caries and comparatively evaluate the roles of Aloe vera and propolis as potential cavity disinfecting agents after minimally invasive hand excavation of dental caries.

Settings and designs: Experimental, in vivo intergroup split mouth, randomized clinical trial.

Subjects and methods: The study included Group I (Control), Group II (A. vera) and Group III (propolis). Ten patients with three teeth each have occlusal/occlusoproximal lesions suitable for ART were selected. Dentinal samples were collected three times from each tooth viz., preexcavation, postexcavation and postdisinfection of the cavities. These dentinal samples were subjected to microbiological analyses for total viable count.

Statistical analysis used: Repeated measures of analysis of variance (ANOVA) with Bonferroni post-hoc test and one-way ANOVA with Tukey post-hoc test.

Results: In all the three groups, significant amount of bacteria were left behind after hand excavation. Group II and Group III, in which cavities were treated with A. vera and propolis extracts respectively, showed a significant reduction in the bacterial counts when compared to control the group.

Conclusions: Hand excavation alone does not completely eliminate bacteria, which may predispose treated teeth to secondary caries. Both propolis and A. vera extracts can be used as potential natural disinfecting agents, thereby embracing the concept of phytotherapy in minimum intervention dentistry.

Figure 1: Comparison of the mean bacterial count between the study groups before excavation, after excavation and after cavity disinfection

Mentions: When inter group comparisons were made using one-way ANOVA [Table 4 and Illustration 1], and pair wise comparisons were done using post-hoc Tukey's test [Table 5], there was no statistically significant difference among the three study groups in the bacterial colony count at two phases of experiment viz preexcavation and also postexcavation. But when bacterial counts were compared postcavity disinfection there were statistically significant differences among the groups (P < 0.01). The reduction in the number of bacterial colonies after cavity disinfection was statistically significant in both Group II and Group III, when compared to Group I (P < 0.001). However, the difference observed between Group II and Group III in terms of TVC after cavity disinfection was not statistically significant (P = 0.99) [Figures 1–9].
